Found these recommended online and seemed like a good deal for the amount of adjustability they provide. Not only did it cover a range of 5-50lbs, but if I ever needed more, I could buy an upgrade to step up the weight exactly as needed. When they arrived, I was also pleasantly surprised to discover that the adjustments were not in 5lb increments, but rather 2.5lb which allows for even smaller steps as needed. The pictures made them look bulky and awkward but they really don't feel any different from traditional dumbbells. Been using for only a coupler of weeks but overall, solid product so far.
